Benefits of technology

[0021] The fuel of the present invention may deliver one of the properties discussed below; however, it is preferred that multiple benefits are delivered by the fuel of the present invention.

Problems solved by technology

The availability and quality of natural resources for jet, gas turbine, rocket, and diesel fuels presents unique and difficult technical challenges.
An identified problem is the increasing demand for jet and diesel fuels for aircraft and for motor vehicles.
Due to the fact that conventional barrels of crude are becoming, on the average, heavier (e.g., more polycyclic) and containing more sulfur, the need for acceptable fuels is an unmet need.
It is believed that highly purified conventional fuels and highly paraffinic Fischer-Tropsch fuels are of lower densities, lack seal swelling abilities, and lubricity.
Significantly increased heat loads are an identified problem as fuel economy / performance considerations raise engine temperatures.
However, such flexibility and diversification is currently not widely available.

Embodiment Construction

[0009] Restrictions on gasoline content, such as benzene, butanes, butanes, and methyl tert butyl ether (MTBE) have made or will make available components which can be used to alkylate aromatics to make monoaromatics used in jet and diesel fuels. The use of monoaromatics as fuels, specifically alkylbenzenes made from benzene and surplus conventional petroleum or Fischer-Tropsch derived propylene and / or butene oligomers (Polygas), may be beneficial in multiple ways. Use of such benzenes and propylene and / or butene oligomers would add to the volume of jet fuel, which is an identified need, while removing undesired materials from gasoline for use in motor vehicles. Additionally the fuel of the present invention has multiple desired properties such as higher flash point, lower pour point, high temperature stability, oxidative stability, increased density, better lubricity, resistance to microbial growth, reduction in toxicity in its own right, and can deliver benefits in blendstocks.

Abstract

A fuel or fuel blendstocks for jet, gas turbine, rocket, and diesel engines, particularly jet and rocket engines utilizing components of conventional petroleum not currently utilized for jet, gas turbine, rocket, and diesel fuels, such as benzene, butanes, butanes, and methyl tert butyl ether (MTBE) alklyated with aromatic moieties to make monoaromatics used in jet and diesel fuels. Additionally, a fuel having such monoaromatics has multiple desired properties such as higher flash point, low pour point, increased density, better lubricity, aerobic degradability, reduction in toxicity, and additionally can deliver benefits in blendstocks.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a fuel or fuel blendstocks for jet, gas turbine, rocket, and diesel engines, particularly jet fuel for gas turbines and rocket engines. BACKGROUND OF THE INVENTION [0002] The availability and quality of natural resources for jet, gas turbine, rocket, and diesel fuels presents unique and difficult technical challenges. An identified problem is the increasing demand for jet and diesel fuels for aircraft and for motor vehicles. As quality requirements for fuels are increasing, the ability to produce acceptable fuels from a conventional petroleum barrel of crude is decreasing. Due to the fact that conventional barrels of crude are becoming, on the average, heavier (e.g., more polycyclic) and containing more sulfur, the need for acceptable fuels is an unmet need. At the same time, the drive for cleaner fuels results in highly hydrogenated, less dense fuels that result from processing to remove sulfur and polycyclics such as n...
